How do I make a video watching app

To create a video watching app, you can leverage several sessions from WWDC that cover different aspects of video playback and user interface design. Here are some key points and sessions that might help you:

Using SwiftUI for macOS Windows:
- You can build a SwiftUI app with scenes like Window and WindowGroup to organize and play videos. Customize each window for the kind of content they present by applying changes to toolbars, window behaviors, and window placements.
- For more details, refer to the session Tailor macOS windows with SwiftUI.
Multiview Video Playback in visionOS:
- AVKit and AVPlayerViewController offer a familiar user interface and integrate with many system features to enhance video viewing capabilities. Multiview allows you to present multiple video screens for simultaneous viewing.
- You can add or remove videos, arrange, reposition, and resize them to get the desired viewing experience. Multiview supports up to five video screens at once.
- For more details, refer to the session Explore multiview video playback in visionOS.
Fullscreen Video Playback:
- To make content fullscreen, size the AVPlayerViewController to match the frame of the window scene. This ensures that even in fullscreen, the AVPlayerViewController will use the 3D video presentation.
- For more details, refer to the session Build compelling spatial photo and video experiences.
Designing a TVOS Media App:
- When building a media app for Apple TV, consider the typical design language, such as a homepage with promoted content, vibrant and colorful lockups, and a tab bar for navigation.
- For more details, refer to the session Migrate your TVML app to SwiftUI.
